Abstract Aiming at investigating the effect of the polymer molecular weight (Mw) on the physical and gas permeation properties of poly(ionic liquid)-ionic liquid (PIL–IL) composites, this work focuses on membranes based on variable Mw pyrrolidinium-PILs having [C(CN)3]– as counter-anion and different amounts (20, 40 and 60 wt%) of free [C2mim][C(CN)3] IL. Although all the prepared composite materials have high thermal stability (Tonset > 556 K) for post-combustion CO2 separation, the evaluation of the film forming ability shows that it is not possible to obtain free standing PIL–IL membranes using the Low Mw PIL (average
